PROBLEM TO BE SOLVED: To reduce diameter and weight by constituting with a long hollow bushing body having many flanges; and a long cylinder extending to the inside of the bushing body, being put into between a conductor and a transition shield, and increasing dielectric constant between the conductor and the transition shield. SOLUTION: A fiber reinforced plastic(FRP) cylinder 32 is put into between a conductor 44 and a transition shield 40 on the inside of a hollow bushing 30 to increase dielectric constant between the transition shield 40 and the conductor 44. The inner diameter of the transition shield 40 is reduced, and the size of the transition shield 40 is reduced as a whole. By placing the transition shield 40 on the outside of the FRP cylinder 32, the separating distance between the FRP cylinder 32 and the transition shield 40 of the bushing is dispensed with. By eliminating a predetermined separation distance, the inner diameter and the outer diameter of the bushing are remarkably reduced.
